The Royal Air Force Museum Cosford, located in Cosford in Shropshire, is a museum dedicated to the history of aviation and the Royal Air Force in particular. The museum is spread over two sites in England, the other site is at the Royal Air Force Museum, Hendon in London.

On 1 May 1979, the Cosford site was opened at RAF Cosford, one of the RAF stations which had been used to store the museum's collection of aircraft. On opening, the museum initially exhibited airframes which had been used for technical training at RAF Cosford. In the following years additional aircraft were added to the collection and in 1980 it was agreed that the British Airways Collection be displayed at Cosford.

On 21 June 1998 four additional galleries were opened, housing art, temporary exhibitions and other aviation subjects. 13 May 2002 saw the relocation of the RAF Museum Conservation Centre from Cardington, Bedfordshire to Cosford. The Centre, costing £2.4 million, was opened by Marshal of the Royal Air Force Sir Michael Beetham and is named after him.
